Apexbio Technology LLC Azido-PEG6-alcohol 86770-69-6 10g
Azido-PEG6-alcohol (CAS 86770-69-6) is a polyethylene glycol-based compound featuring an azide functional group It serves as a versatile building block in bioorthogonal conjugation strategies particularly in click chemistry applications The azide moiety allows it to participate in copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) with alkyne-containing molecules as well as strain-promoted azide-alkyne cycloaddition (SPAAC) with DBCO- or BCN-functionalized compounds These properties enable its use in the synthesis of antibody-drug conjugates (ADCs) and in preparing diverse bioconjugates for biomedical research
